Xenes,包括单元素原子片,表现出狄拉克或类似狄拉克的量子行为。当与六方氮化硼(hBN)等其他二维(2D)材料连接时,过渡金属二硫属化合物(TMDC),和金属碳化物/氮化物/碳氮化物(MXenes),它们显示出在单个组分中无法获得的协同物理和化学特性。Xenes与特定功能2D材料的战略杂交能够实现独特的物理化学性质,包括结构稳定性,理想的带隙,有效的电荷载流子注入,柔韧性/断裂应力,热导率,化学反应性,催化效率,分子吸附,和润湿性。例如,hBN作为抗氧化屏障,MoS2在激光激发时注入电子,和MXene提供机械灵活性。除了精确的成分调制,堆叠序列,和由参数控制的层间耦合,在杂交中实现可扩展性和再现性对于在消费者应用中实现这些量子材料至关重要。然而,实现这些混合材料的全部潜力面临着诸如气隙,不均匀的接口,以及缺陷和官能团的形成。先进的合成技术,对量子行为的深刻理解,精确控制界面相互作用,意识到这些因素之间的相互关系是至关重要的。基于Xene的混合动力在量子计算领域的突破性应用显示出巨大的前景,柔性电子,储能,和催化。从这个及时的角度来看,我们强调最近发现的新Xenes及其杂种,强调合成参数之间的相关性,结构,属性,和应用。我们预计这些见解将彻底改变不同的行业和技术。本文受版权保护。保留所有权利。
Xenes, mono-elemental atomic sheets, exhibit Dirac/Dirac-like quantum behavior. When interfaced with other 2D materials such as boron nitride, transition metal dichalcogenides, and metal carbides/nitrides/carbonitrides, it enables them with unique physicochemical properties, including structural stability, desirable bandgap, efficient charge carrier injection, flexibility/breaking stress, thermal conductivity, chemical reactivity, catalytic efficiency, molecular adsorption, and wettability. For example, BN acts as an anti-oxidative shield, MoS2 injects electrons upon laser excitation, and MXene provides mechanical flexibility. Beyond precise compositional modulations, stacking sequences, and inter-layer coupling controlled by parameters, achieving scalability and reproducibility in hybridization is crucial for implementing these quantum materials in consumer applications. However, realizing the full potential of these hybrid materials faces challenges such as air gaps, uneven interfaces, and the formation of defects and functional groups. Advanced synthesis techniques, a deep understanding of quantum behaviors, precise control over interfacial interactions, and awareness of cross-correlations among these factors are essential. Xene-based hybrids show immense promise for groundbreaking applications in quantum computing, flexible
electronics, energy storage, and catalysis. In this timely perspective, recent discoveries of novel Xenes and their hybrids are highlighted, emphasizing correlations among synthetic parameters, structure, properties, and applications. It is anticipated that these insights will revolutionize diverse industries and technologies.
